Bug Description
I followed http://
---------- snip ---------------
HIBERNATE_
# Always use hibernate instead of suspend, but with "suspend to both"
if [ "$METHOD" = "suspend" ]; then
METHOD=hibernate
HIBERNATE_
fi
# Make sure to use the kernel's method, in case uswsusp is installed etc.
SLEEP_MODULE=kernel
---------- snip ------------------
On suspend, the system writes an image to disk (according to /var/log/syslog) and goes to sleep on RAM as expected. However, on resume things first seem to proceed normally, but the screen is never lit up. I couldn't find any obvious errors in /var/log/syslog.
The behaviour is similar with the "Indirect hybrid sleep" approach, which used to work successfully before upgrading from 13.10 to 14.04.
Both suspend-to-RAM and suspend-to-disk (hibernate) work and resume sucessfully, i.e. when removing the file /etc/pm/
